The Corsair iCUE LINK H150i RGB is a solid offering from the company that pioneered AIO liquid coolers, bringing them into the mainstream years ago. While it doesn't claim the top spot, it engages in a back-and-forth competition depending on the test platform with its sibling, the Corsair H150i Elite LCD XT. In both maximum RPM and in the noise-normalized 45 dBA tests, the new iCUE LINK H150i RGB managed to control the AMD Ryzen 7900X, even in the extreme 225 W heat load test. In terms of maximum heat load it could handle, it survived up to 240.9 watts, compared to the LCD XT model, which was capable of handling 250.7 watts. Switching to the Intel 13700K saw the two swapping places. Corsair's new iCUE LINK model managed to handle 339.6 watts, while the LCD XT model fell behind a bit at 331.6 watts. The Lian Li Galahad II Trinity Performance 360 still holds the overall crown in terms of maximum performance with a hefty lead on AMD; however, on Intel, the gap is quite small.

Unlike previous generations, if you're running a higher-end CPU with incredibly dense transistors, going with a 360 mm liquid cooler isn't a bad idea. As shown in the AMD tests, the current 360 mm AIOs easily keep the CPU cool enough for optimal performance even under extreme situations, with noise levels kept in check. This is something most other coolers, including 240/280 mm AIOs, and even the venerable Noctua NH-D15 and DeepCool Assassin IV, are not capable of.

Overall build quality is good, and the mounting hardware is easy to work with. New features like the iCUE LINK passthrough on the radiator are a welcome addition that, while not truly new to market, has been added and adapted to make cable management far easier than in previous Corsair liquid coolers. Additionally, older but no less useful features such as the zero RPM fan mode via iCUE software contribute to a fully-featured product that ticks all the right boxes. The only real downside is the high cost of entry, with the iCUE LINK H150i RGB being relatively expensive compared to other 360 mm AIOs on the market. That said, a six-year warranty somewhat offsets that cost, as more affordable AIO liquid coolers typically have much shorter warranty periods.

My only real gripe is that while Corsair is addressing cable clutter and other issues, they use a semi-proprietary connector for the fans, etc. This means that if you ever wanted to repurpose the fans, you better hope the software and iCUE LINK hub don't change because you may end up with useless parts. This limitation restricts the ability to reuse perfectly good fans if something goes wrong, unlike other designs with standard 4-pin PWM connectors and standard ARGB headers that won't need to worry about it. Other than that, the only oddity is the use of a PCIe 6-pin connector to power the iCUE LINK hub. It's not necessarily good or bad, just a bit strange. However, it does offer the ability to handle far more devices than, for example, a SATA or MOLEX connector. In that sense, I don't see a huge issue with it; just make sure your PSU has a spare 6-pin PCIe connector handy.

Overall, the Corsair iCUE LINK H150i RGB is an excellent cooler that offers a visually appealing design with near-chart-topping performance. Adding in unique features along with a class-leading warranty, I see very few reasons not to recommend it, especially if you're already invested in the Corsair ARGB ecosystem.
